Garner Creek Case Study Essay

The health of the Susquehanna River and Chesapeake Bay was found based on Biological (macroinvertebrates and wildlife) and Chemicals characteristics (pH, dissolved oxygen, phosphates, nitrates, etc.) as well as physical observations (amount of forested buffers, wetlands, etc.) Overall it was concluded that the health of the water was good to excellent. What was found was that many of the macroinvertebrates found in the water were sensitive or facultative, meaning the water quality was good enough for them to live in. Also, the level of ph, temperature, dissolved oxygen, phosphates, nitrates, and turbidity showed that the water quality was good. Finally, while we were canoeing down the Susquehanna River, observations were made on the land

Silver Creek Wetland Complex is a rare coastal wetland found along the eastern side of the Nottawasaga Bay Shoreline. It falls within the town boundary of the Town of Collingwood, which was formally a part of the Town of Blue Mountains. Because the area is a part of the greater Silver Creek Watershed, the marshy land is classified as a Schedule B Category 1 land under Environmental Protection as per the Official Plan of the Town of Collingwood. Blue Mountain Trust Watershed Practice monitors the watershed and the significant wetland is protected and maintained by Nottawasaga Valley Conservation Authority. The 2700 Ha watershed flows through the “Lake of Clouds” by Castle Glen, down the Niagara Escarpment, where the 160 Ha complex at the

The change in season’s results in differences in the flow, size and overall function of the lake, stream, or river and therefore the constant monitoring of these systems are beneficial to determine ecosystem characteristics and patterns (Lenat, 1988).

Each person got to test either the phosphates, nitrates, dissolved oxygen, or the ph in the creek. Phosphates and nitrates are nutrients found in water due to fertilizers, decaying plants and bacteria. Dissolved oxygen is the amount of gaseous oxygen dissolved in the water. As we recorded our results, we discovered that the dissolved oxygen levels were very high, which is good because the higher amount of dissolved oxygen in the water, the healthier the creek is. The phosphates levels in the creek were all perfect zeros, which is great because having nutrients in the creek is not healthy. The nitrate levels were slightly higher, at 0.9. That is not bad at all, but it isn’t perfect, showing signs of pollution. The ph levels in the rocks were neutral, right at seven. If they were lower than 7, that would mean they have acids in them, and if they were higher than 7, they would have alkaline in them. Alkaline, or bases, neutralizes acids. The number of rocks that we found that neutralized acid was 65, and the number of rocks that did not neutralize acids were 29. This shows that about one-third of the rocks in the creek do not neutralize acids.

A site called Coobool Creek on the Wakool River, located between Swan Hill and Deniliquin in the Murray River Valley was where G. M. Black accumulated 126 skulls from the suface area near Doherty’s Hut at the Coobool Crossing in 1950 and they were studied by Brown. The 126 crania has been returned to the Aborigines for a reburial. The collection was named the Murray Black collection after G. M. Black who found it and the location in which in was found.

The issue is the idea of the second airport being constructed at Badgerys’s Creek. This affects the environment of Badgerys’s Creek greatly as it can destroy such a beautiful site.

Either or both of those two things could have runoff from the land and drained into the creek. They are negative to the creek. Our results showed that the creek was containing little to no phosphate. The average number after 15 tests was just 0.3- zero being the best. Similarly, nitrate is a salt or ester, but it is made of nitric acid, containing the anion NO3. It is found in runoff from fertilized farms and treatment plants. The same process was used for testing nitrate levels. The average level out of eight tests was 0.8, which is a higher than phosphate but still relatively low. Both of those test results were very positive. It showed that the creek was low in eutrophication. Another chemical test is testing for dissolved oxygen. Dissolved oxygen is microscopic bubbles of oxygen (O2) that are in the water and there for aquatic organisms to breathe in, which is necessary for almost all organisms. The testing process was similar to that of nitrate and phosphate tests. After testing the water, we got an average level of 11.4. More dissolved oxygen allows for more gaseous bubbles for organisms to breathe in. Therefore, a higher number is better. Twelve is the highest level of dissolved oxygen possible. Thus, since 11.4 is very close to 12, the dissolved oxygen level was very good. Dissolved oxygen can be changed in a number of ways. First, stagnant, or not moving, water has a much lower level of dissolved oxygen. Also, hotter water has less dissolved water. Lastly, chemicals like phosphate and nitrate can cause the growth of algae (which will be discussed in more detail in paragraph three), taking away oxygen. Additionally, the students tested for acid rain pollution. The tests falling under the acid rain category would test for acidity or alkalinity in water. We took a pH test, which is a level expressing the

Charleston, South Carolina boasts a rich history. The city was founded in 1670 by English colonists and grew from a small to a prosperous seaport (Charleston, n.d.). The Civil War’s beginning was at Charleston’s Fort Sumter as Confederate soldiers fired upon Union soldiers in April of 1861 (Charleston, n.d.). The Civil War was difficult to recover from for Charleston, and in its rebuilding it focused on trade and industry (Charleston, n.d.). As time went by, Charleston was challenged with a “dying downtown and a crumbling urban housing stock” (Jackson & Sinclair, 2011, p. 80). In 1976, Mayor Joseph “Joe” Riley took office and was the catalyst in the rehabilitation of the city, making it one of the most beautiful American cities today (Jackson & Sinclair, 2011). This paper will summarize the case study of Charleston, South Carolina, which is segmented into four sections, the Symptoms, the Diagnosis, the Cure, and the Prevention.

The removal method of Ringed Crayfish data collection was over a sample site area of 50m2 at Pearson Creek, a stream, containing a density of 5.18 crayfish/m2. The sample site was collected in 5m in width by 10m in height with wet, rocky, and grassy conditions. The data collection incorporated five different samples of the number of crayfish removed from the stream each time (Figure 1). Sample one caught 53 Ringed Crayfish with 0 crayfish caught prior. Sample two caught 37 Ringed Crayfish with 53 crayfish caught prior. Sample three caught 42 Ringed Crayfish with 90 crayfish caught prior. Sample four caught 26 Ringed Crayfish with 132 crayfish caught prior. Sample five caught 18 Ringed Crayfish with 158 crayfish caught prior. What was caught in the previous sample was added into the total amount of crayfish caught prior. A negative linear relationship is displayed by data collected in Figure

In summary, there are many different factors that contribute to the health of the Susquehanna River. The factors include the pH, temperature, phosphate, nitrate and dissolved oxygen levels. Another factor is the wildlife living in and around the water. A healthy pH level is from five to eight. The tested level was within this range! The temperature was also at a good level because it was cold enough to have the healthy level of dissolved oxygen. The dissolved oxygen level was about nine. The nitrate levels were excellent, but the phosphate levels were just good because they were slightly above where they are supposed to be. Also, by analyzing the types of macroinvertebrates in the river, the level of pollution can be evaluated. The

The average temperature was approximately 9.67 C. The temperature of the water is significantly impacted by the amount of cool wind the area receives, the amount of sunlight, and the time of year in which the temperature was measured. These factors allow for the water to maintain significantly cooler throughout the year. Also affected by wind are the velocity and rate of flow of the stream. The average velocity is 0.29 meters per second (m/s) and the rate of flow is 41.30 meters3 per second (m3/s). The velocity and rate of flow in the area are higher because it was closer to the dam and also contained areas that were more elevated than some. Sunlight, on the other hand, also affected the turbidity and the photic zone. The turbidity of the stream was 26.50 centimeters (0.265 meters), while the photic zone was 0.42 meters. The photic zone is the depth of the water that receives the greatest amount of sunlight that is then used to carry out photosynthesis. Turbidity is an indicator of how much algae or sediments is present in a lake because it affects the visibility of the water. The cloudiness of the water is caused by the dissolved particles scattering light molecules within the water. The average depth of the water is 9.50 meters and the average width of the water is 14.99 meters. The measurements of the width and depth are not affected by anything. According to Trout

This lab investigates the question, What is the water quality of the U-High stream based on water invertebrates found? Water quality can be determined by multiple factors such as clarity, pH, dissolved oxygen, and levels of pollution. Clarity is the amount of sediment in the stream, higher amounts of sediment is unhealthy for water quality. pH measures the acidity or basicness of the stream, a healthy stream has a pH between 6.0-9.0. Dissolved oxygen is the level of oxygen in the water, this is necessary for the survival of organisms, higher measurements means better water quality. Finally different types of pollution can affect water quality such as nitrogen and phosphorus. Too much of either chemical can cause eutrophication which leads

Having a variety of organisms is one of the most important things in a aquatic ecosystem. In order to have the you must have a ecosystem with little polutance so organisms can live. (River Watch) The water quality was 36, therefor the water quality was excellent. The index was so high because many organisms were found in the water.

By setting an amount of tests that would be conducted we allowed for an even number of tests between water temperatures. The amount of tests that were conducted were chosen with considerations, these included: the amount of time given to complete the experiment, the work force granted to complete the experiment and the equipment able to be supplied and used. This allowed for the optimal amount of tests to be conducted and allowed for accurate data collection. This experiment allowed for conclusions to be drawn and uses to be analysed. The use of this experiments results and conclusions in society are: allows for the optimal temperature to be chosen to purify water with the least time loss. This could be useful in survival situations and recreational activities, where time is

Within this task we were required to determine the ecological state of the Reddam House wetland, which I presume is at a good standard.
